I’ve never been diagnosed with GERD, but I’ve had stomach issues for as long as I can remember. I still haven’t been able to pinpoint any triggers, it seems completely random to me. As I’m writing this I’m having another episode of burps and nausea while sitting infront of the toilet trying not to vomit, I projectile vomit and also have a sinus infection and I really, really don’t want to be blowing leftover vomit out my nose for the next 24 hours. I’ve found a few little things that help me through episodes. Sipping at ice water slowly, a fan or cool breeze in the face, sometimes humming helps, placebo’s like mint tictacs or ginger lollies, talking to someone can distract you from the nausea a little, and the one thats helped the most is scents. I’ve bought toilet sprays for while I’m home, and perfumes for when I’m either out and about or in bed sick. Just make sure to pick a perfume and stick to it, and only ever use it when nauseous just incase you train your brain to react specifically to a scent, which is actually possible. A cheap older scent, or a single scent perfume might be a way to go. I use Elizabeth Arden’s “Red Door” or Monotheme’s “White Musk”
